Is there a cure of ocd?

No: But there is plenty of help. Ocd like many other disorders such as diabetes, hypertension, arthritis and mood disorders can be treated successfully, but often require long term treatment so the disorder does not seriously impair a persons function and they can live a fairly normal life. The best care is counseling, desensitization and medication combined. A strong positive attitude helps also.

OCD like high blood: Pressure is managed, not cured---yet.

GET THEE E.R.P. !: There is effective behavioral treatment for ocd. It's possible to gain control of ocd & learn to stop it from running your life! the "gold standard" treatment is behavioral: it's called exposure & response prevention. Find an ocd expert to help. See resources on the international ocd foundation website: www.Ocfoundation.Org. Meds can be big help too.

Meds and therapy: Meds (usually antianxiety medications, but not always) combined with therapy with a clinician who specializes on OCD is the best combination to treat OCD, typically.
